You’re staring at your map in Pokémon Scarlet or Violet, and there it is. That pulsing red icon. A mass outbreak. Most players see these as just a way to fill the Pokédex or maybe snag a few extra materials, but if you’re actually trying to find a shiny or a rare Mark, you’re likely doing way more work than you need to. Honestly, it’s kinda funny how many people still think you have to catch every single Pokémon in the area to make the "rare" ones show up.
That’s not how it works at all.
Pokemon mass outbreak events are special, limited-time windows where specific, often region-locked or rare Pokémon flood the map. We’re talking about things like Clefairy appearing in Paldea when they’re usually stuck in Kitakami, or the recent 2026 events featuring the "Mighty" starters and their outbreaks. But to actually win at these events, you have to understand the math behind the spawns.
The 60-KO Rule (And Why Numbers Matter)
Basically, your shiny odds in a standard encounter are trash. 1 in 4,096. That’s the base. When you step into an outbreak, those odds don't just magically jump up immediately. You have to "prime" the outbreak first.
You’ve probably seen those messages pop up in the corner of your screen. "The outbreak is starting to grow smaller" or "There are not many Pokémon left." Those aren't just flavor text. They are your progress bars.
- 30 KOs: Your first real bump.
- 60 KOs: This is the sweet spot.
Once you’ve defeated 60 Pokémon in that specific outbreak—usually by using the "Let’s Go" auto-battle feature—your shiny odds hit their peak for that event. If you have the Shiny Charm, your odds at 60 KOs drop to roughly 1 in 819. If you add a Level 3 Sparkling Power sandwich to the mix? You’re looking at 1 in 512.
But here is where everyone messes up: they keep killing them after 60.
Stop. Just stop. Once you hit that 60 mark, you don't need to defeat another single Pokémon. In fact, if you keep going, you might accidentally end the outbreak entirely. Once the "odds are maxed," your goal shifts from "extermination" to "refreshing."

Why the Picnic Reset is Your Best Friend
You don't need to run halfway across the map to get new Pokémon to spawn. You just need to make them go away for a split second.
Opening a picnic and immediately closing it acts like a "refresh" button for the entire area. You stand in the middle of the outbreak, pop the picnic, exit, and—boom—15 new spawns appear instantly. If none of them are sparkly, you do it again. It takes five seconds.
Some people prefer the "town reset" where you just step over the line into a city and back out, but the picnic method is universal. It works in the middle of the wilderness or the top of a mountain.
Special Event Outbreaks Are Different
It's worth noting that "Event" outbreaks—the ones with the special glowing aura on the map—often have built-in bonuses. During certain 2025 and 2026 events, Game Freak has boosted the "Mark" chances or even given a flat 1/200 shiny rate for specific weekends. If you're hunting during a special window, check the Poké Portal News first. You might not even need a sandwich if the base event odds are high enough.
The Sandwich Science (No, You Don't Need Salty Herba)
There is a huge misconception that you must have Salty Herba Mystica to make a good shiny sandwich. That’s old news. While Salty is the easiest "catch-all" ingredient, you can actually use any combination of Herba Mystica (Sweet, Sour, Spicy, Bitter) if you know the right filler ingredients.
For example, if you're hunting a Fairy-type like Clefairy or Florges during an event:
- 1 Tomato
- 1 Salty Herba + 1 Spicy Herba (OR any two except the Sweet/Sour combo)
This gives you Sparkling Power: Fairy Level 3 and Title Power: Fairy Level 3. Title Power is huge because it increases the chance of your Pokémon having a Mark, like the "Upbeat Mark" that was featured in the Clefairy outbreak event.

Legends Arceus vs. Scarlet/Violet Outbreaks
If you’re coming from Pokémon Legends: Arceus, the system here might feel a bit chaotic. In Arceus, you had "Massive Mass Outbreaks" that were tied to rainstorms. They were high-pressure, timed events where you had to clear multiple hordes before the storm ended.
In Scarlet and Violet, the pressure is gone. The outbreaks last for the entire real-world day. You can take your time. You can save your game before making your sandwich, and if you don't find a shiny within the 30-minute timer, you can just close the game and restart. You get your rare Herba Mystica back, and you can try again. It’s much more "cheesable" than the Arceus system.
Common Mistakes to Avoid
- Not Saving: For the love of Arceus, turn off auto-save. Save manually before you start the hunt. If you see a shiny and it self-destructs or runs away, you can just reload.
- Killing the Shiny: Don't use "Let's Go" once the 60 KOs are done. Your Pokémon won't actually kill a shiny in auto-battle, but why risk it? Just walk up and initiate a regular battle.
- Ignoring the Map: Event outbreaks sometimes spawn in weird places, like the Terarium in Blueberry Academy or the mountains of Kitakami. If you don't see the icon, you might need to update your Poké Portal News in the Mystery Gift menu.
Actionable Next Steps for Your Next Hunt
To maximize your time during the next pokemon mass outbreak events, follow this specific workflow to ensure you aren't wasting hours for nothing.
- Check the Calendar: Open the Poké Portal and see which Pokémon are currently featured. Event outbreaks often have much better Mark or Shiny odds than the random daily ones.
- Clear 60: Use a fast Pokémon (like Varoom or Gholdengo) to auto-battle exactly 60 of the target species. Use a counter on your phone if you have to.
- Hard Save: Stop everything. Save your game right there in the middle of the empty field.
- Eat the Sandwich: Use your Herba Mystica to craft a Level 3 Sparkling/Title/Encounter sandwich for the specific type you're hunting.
- The Picnic Loop: Instead of running around, stand still and open/close your picnic to refresh spawns every 10 seconds.
- Reload if Necessary: If the 30-minute sandwich timer runs out and you didn't get your prize, close the game without saving. You’ll be back at the 60-KO mark with all your ingredients intact.
This is the most efficient way to handle outbreaks in the current 2026 meta. It saves your resources, protects your sanity, and statistically guarantees you the best possible luck the game allows.
